How to reindex the content of your course
If your search features don't seem to be working properly, it might be because your course needs to be reindexed.
Whenever you change something about the content of your course, you'll need to reindex the course. This allows the Open edX search engine to index everything in the course so that when students use the search feature, they'll be able to find what they're looking for.
Reindexing is very simple. Here's how it's done:
Navigate to Open edX Studio of the course you've recently edited, and click "Reindex"
It's really that simple!
As soon as it's done (a process that takes anywhere from a few seconds to a few minutes, depending on how big your course is), you'll receive a message like this:
Now your students will be able to use the search features of Open edX!
